We have a proof on concept project for a wearable wireless device that can transmit data to a central receiver. Following a successful validation we will be looking to produce 1000+ units (of the device)

I am currently putting together a proposal for the POC/validation and looking for people to help.

You talking the equivalent of a promini, nRF24L01 type of transceiver, MAX1811 LiPo battery charger and a LiPo battery?Central receiver pings each transmitter for status to avoid transmitter conflicts?I can design the card and work with an assembly house in CA that does automated pick & place assembly for $4-6/card and $300-400 for stencil & pick & place programming (but depend on complexity).
